renard-phy-s2lp-hal-stm32 - STM32L0 Hardware Abstraction Layer for renard-phy-s2lp
renard-phy-s2lp-hal-stm32 is the STM32L0 hardware abstraction layer (HAL) for the open source Sigfox PHY layer renard-phy-s2lp, which interfaces with STMicroelectronics' S2-LP ultra-low power transceiver chip.
See renard-phy-s2lp for more information.
renard-phy-s2lp-hal-stm32 has multiple GPIO configuration profiles: One of them is compatible with STEVAL-FKI868V2, the other one with HT Micron's HT32SX. They use the following pins to interface with the S2-LP:
| S2-LP Pin Name | STM32 Pin | HT32SX Pin |
|---|---|---|
| MISO (SPI) | GPIOA 6 | GPIOB 4 |
| MOSI (SPI) | GPIOA 7 | GPIOA 7 |
| SCLK (SPI) | GPIOB 3 | GPIOB 3 |
| CS (SPI) | GPIOA 1 | GPIOA 15 |
| SDN | GPIOA 8 | GPIOB 8 |
| GPIO3 | GPIOC 0 | GPIOB 2 |
To select your desired configuration profile, use the compile time define switches -DRENARD_PHY_S2LP_HAL_STM32_CONF_FKI868V2 (for FKI-868V2) or -DRENARD_PHY_S2LP_HAL_STM32_CONF_HT32SX (for HT32SX). To add your own GPIO profile(s), take a look at conf/conf_hardware.h and the provided profiles in conf/presets_hardware. Pull requests for additional profiles are welcome!
See renard-phy-s2lp-demo-stm32 (FKI-868V2) or renard-phy-s2lp-demo-ht32sx (HT32SX) for sample code that demonstrates how to integrate this HAL together with renard-phy-s2lp into your project.
